The game isn't rigged. The CPU just knows the rules already and it already knows what to play after it rolls; you don't unless you've played a game like this before. There's a learning curve.
Average game. Graphics are good. Music is too. The game play is where it falls short. Battles are more or less "point and click here" chore. There's not much depth to it.
Strategy: Spam the weaker enemy cells first. Use the tiny neutral cells as bases. When the enemy tries to take neutral large cells, let them do all the work (and use that time to grow); allow to reduce the neutral cell defense to/near 0, so you can take it instead.
The game gets easier once you let the AI do the work for you. Good concept, it just takes a bit to learn...
The improvements and addition to the gameplay of the previous game are perfect; it adds something new and it's still fun to play.
And who can resist mowing down a zombie with a chainsaw?
It would be nice if there were a way to zoom in and out on the map. Scrolling across the screen is somewhat bothersome. Also, a control panel for created units with their type, current comand, and location would be extremely useful.
